My wireless mouse has just started to play up, I have had to up the speed of the pointer as i had to move my mouse right across the desk just to move the pointer across the screen, ( the batteries are ok ) also I now have to click loads of times to open any thing. Have tried restore but its just the same.

Is it relatively new? As in returnable?

Was any software especially installed for it?

Have you tried new batteries just to be sure?
